Description

This might be related to a change in the Android SDK or maybe in the MAUI keyboard/View implementation, but disabling a RefreshView with refreshView.IsEnabled = false disables keyboard entry into textareas (and probably inputs too) in MAUI Blazor. Haven't had the chance to try if native inputs were affected yet.

Steps to Reproduce

1. Create a new MAUI Blazor Hybrid project
2. Wrap the BlazorWebView in a RefreshView
3. Set IsEnabled on the RefreshView to false
4. Add a textarea to the Razor view
5. Run the application, tap into the textarea and start typing
6. Caret doesn't appear, input is ignored

Is this a regression from previous behavior?

Affected platform versions

Did you find any workaround?

Yes, we're currently using the following workaround:

// Platforms/Android/CustomDisableSwipeRefreshLayout.cs
public class CustomDisableSwipeRefreshLayout : MauiSwipeRefreshLayout
{
    public bool DisableRefresh { get; set; }

    public CustomDisableSwipeRefreshLayout(Context context) : base(context)
    {
    }

    public override bool CanChildScrollUp()
    {
        if (DisableRefresh)
            return true;

        return base.CanChildScrollUp();
    }
}

with a custom ViewHandler, we are abusing CanChildScrollUp to disable refresh without disabling the Control itself, and then setting it directly:

// Platforms/Android/ViewHandlers/RefreshViewHandler.cs
public class RefreshViewHandler : Microsoft.Maui.Handlers.RefreshViewHandler
{
    protected override MauiSwipeRefreshLayout CreatePlatformView()
    {
        return new CustomDisableSwipeRefreshLayout(Context);
    }
}

// MauiProgram.cs
handlers.AddHandler<RefreshView, RefreshViewHandler>();

// Usage
#if ANDROID
    if (RefreshViewInstance.Handler?.PlatformView is CustomDisableSwipeRefreshLayout platformView)
    {
        platformView.DisableRefresh = !isReloadable;   
    }
    else
    {
        RefreshViewInstance.IsEnabled = isReloadable;
    }
#else
    RefreshViewInstance.IsEnabled = isReloadable;
#endif

Obviously, it would be nicer to inherit from RefreshView and fully implement this in the MAUI view itself, but this works as a quick and dirty patch.
